Cold Roll Forming Machine, Steel Ball Guided Rail Machine Roller Design and Manufacturing Features:

1. Principle of average force distribution across all stages, even force distribution across the full line of roller wheels, even wear, and extended roller lifespan.

2. The use of C12MoV material for rolling mill rolls takes advantage of its wear resistance, but there is a contradiction between its strength and hardness. During heat treatment, the red hardness of C12MoV must be utilized, and the hardness can only be achieved after two or even three tempering cycles following quenching.

3. The track arc section is the core part of the slider. After the initial forming of the arc through several passes, during the subsequent folding of the standing edge, the formed arc should be effectively constrained through the upper and lower roller or cross wheel. Otherwise, the arc position of the material will certainly change during the stretching process, with R becoming triangular, the steel ball not reaching the bottom, resulting in noise from the two-point contact. When R becomes larger, it causes oscillation with the track, making the slider's path unclear during use, unevenly distributed forces, deforming the slider, and shortening its lifespan.

4. Rolling stability issues often arise during production, where the material tends to sway left or right within the roller track. This is actually due to the uneven distribution of force on a single roller set, with more force on the left causing the material to sway to the right, and vice versa on the right.
